Miscellaneous reactions

Ebook "Synthesis and modification of heterocycles by metalcatalyzed cross-coupling reactions" e is focused on new and innovative metal-catalysed reactions that lead to the formation of a carbon–carbon or a carbon–nitrogen bond. In the first chapter brings all types of crosscoupling methods covering mainly the literature from the past decade.

Ebook "Cellulose derivatives: Synthesis, structure, and properties" summarizes recent progress in cellulose chemistry. The last 10 years have witnessed important developments, because sustainability is a major concern. Biodegradable cellulose derivatives, in particular esters and ethers, are employed on a large scale. The recent developments in cellulose chemistry include unconventional methods for the synthesis of derivatives, introduction of novel solvents, e.g.

Ebook "Chemical transformations of vinylidenecyclopropanes" review their investigations on the chemistry of VDCPs, mainly including the preparation, the reactivities upon treatment with Lewis or Brønsted acid, as well as transition metal catalysts and some other miscellaneous analogues. The contributions aroused a renaissance of cationic intermediates in the chemistry of VDCPs.

Heterocyclic Chemistry represents a vast and important area of research which is of interest to a wide spectrum of chemists. This is amply documented by the fact that various journals, societies, and interest groups have sprung up entirely devoted to the pursuit of heterocyclic chemistry. Surprisingly though, there exists to our knowledge no single periodical review alerting the reader on an annual basis to important developments of the subject. We have now been able to persuade...

Hydrogen peroxide is particularly effective when it reacts with ferrous iron (Fe2+ ) to produce Fenton's Reagent. Ferrous iron may be naturally present in the subsurface soils and/or groundwater, or it can be added as a catalyst solution together with the hydrogen peroxide to produce this aggressive chemical reaction. Hydrogen peroxide in the presence of ferrous iron (Fe2+ ) reacts to form hydroxyl radicals (OH•), ferric iron (Fe3+ ), and hydroxyl ions (OH- ). The hydroxyl ions are very powerful oxidizers, and react particularly with organic compounds.

Amines are extremely important intermediates and end products of the chemical industry and are often obtained by hydrogenation of the corresponding nitro compounds or imines. A search of the literature reveals, that hydrogenation of nitro compounds catalyzed by well-defined molecular complexes in aqueous solutions is rare.

The realm of aqueous organometallic catalysis incorporates many more reactions and catalysts than discussed in the preceeding chapters. However, these were not investigated in so much detail as, for instance, hydrogenation or hydroformylation; some of them are mentioned only here and there. An attempt is made to give a representative sample of these studies.
